zfs discuss - Aug 2009 - cannot restore to [snapshot]: destination already exists

I''m running into a problem trying to do "zfs receive", with
data being replicated from a Solaris 10 (11/06 release) to a storage server
running OS 118. Here is the error:

root at lznas2:/backup# cat backup+mcc+users\@zn2---pre_messages_delete_20090430
|  zfs receive backup/mcc/users
cannot restore to backup/mcc/users at pre_messages_delete_20090430: destination
already exists
root at lznas2:/backup# 

(Incidentally, this web form won''t let me post a less-than redirect
character, as in "zfs receive [less-than] file")

It seems not to like the snapshot name, as specifying a different snapshot name
does work:

root at lznas2:/backup# cat backup+mcc+users\@zn2---pre_messages_delete_20090430
| zfs receive backup/mcc/users at some_other_name


...but I could find no evidence of the snapshot which "already
exists":

root at lznas2:/backup# zfs list -t all -r backup/mcc/users
NAME                   USED  AVAIL  REFER  MOUNTPOINT
backup/mcc/users      2.31G  1.90T  2.29G  /backup/mcc/users
backup/mcc/users at zn2      0      -  2.29G  -
root at lznas2:/backup# 

root at lznas2:/backup# zfs list -t all  | grep pre_messages_delete
root at lznas2:/backup# 

I tried renaming backup/mcc/users, resending it from the production system &
the fresh copy still produces the error when I try to apply that snapshot.

Thanks!

How was the file created?

I believe I had just redirected zfs send to a file, then ftp''ed the
file. I tried that after my script had been producing the error. It had been
trying to do "zfs send | socat | zfs receive" essentially.
